Because macroeconomists have messed it up for every one else , says Noah Smith at The Week:

To put it mildly, economists have fallen out of favor with the public since 2008. First they failed to predict the crisis, or even to acknowledge that such crises were possible. Then they failed to agree on a solution to the recession, leaving us floundering. No wonder there has been a steady flow of anti-economics articles (for example, this, this, and this). The rakes and pitchforks are out, and the mob is ready to assault the mansion of these social-science Frankensteins.

But before you start throwing the torches, there is something I must tell you: The people you are mad at are only a small fraction of the economics profession. When people in the media say “economists,” what they usually mean is “macroeconomists.” Macroeconomists are the economists whose job is to study business cycles — booms and busts, unemployment, etc. “Macro,” as we know it in the profession, is sort of the glamor division of econ — everyone wants to know whether the economy is going to do well or poorly. Macro was what Keynes wrote about, as did Milton Friedman and Friedrich Hayek.

The problem is that it’s hard to get any usable results from macroeconomics. You can’t put the macroeconomy in a laboratory and test it. You can’t go back and run history again. You can try to compare different countries, but there are so many differences that it’s hard to know which one matters. Because it’s so hard to test out their theories, macroeconomists usually end up arguing back and forth and never reaching agreement.

Meanwhile, there are many other branches of economics, doing many vital things.

What are those vital things? Some economists find ways to improve social policies that help the unemployed, disabled, and other vulnerable populations. Others design auctions for Google. Some evaluate development polices for Kenya. Others help start-ups. And on and on. Love it or hate it, their work should be judged on its own merits, not lumped in with the very different world of macroeconomics.

The Council of Economic Advisers just released an interesting paper examining the macroeconomic harm from the government shutdown and debt limit brinksmanship. To do so, they created a Weekly Economic Index from data that are released either daily or weekly (and weren’t delayed by the shutdown). These data include measures of consumer sentiment, unemployment claims, retail sales, steel production, and mortgage purchase applications.

The headline result: They estimate that the budget showdown cost about 120,000 jobs by October 12.

Looking ahead, I wonder whether this index might prove useful in identifying future shocks to the economy, whether positive or negative. As the authors note:

In normal times estimating weekly changes in the economy is likely to detract from the focus on the more meaningful longer term trends in the economy which are best measured over a monthly, quarterly, or even yearly basis. But when there is a sharp shift in the economic environment, analyzing high-frequency changes with only a very short lag since they occurred can be very valuable.

P.S. I am pleased to see CEA come down on the right side of the “brinksmanship” vs. “brinkmanship” debate.

Ray Dalio, founder of the remarkably successful Bridgewater Associates, has released a 30 minute video explaining his vision of “How the Economic Machine Works.” Well worth watching, particularly his description of a beautiful deleveraging.

James Bullard, head of the St. Louis Federal Reserve Bank, gave a nice presentation on “The Tapering Debate” today. See the whole thing here.

One question he considers is whether the Fed balance sheet is getting scarily big. It’s certainly large by U.S. historical standards — the only time is was bigger, relative to the size of the economy, was in the 1940s.

By current international standards, however, the Fed balance sheet isn’t an outlier. In fact, Japan, Europe, and the United Kingdom all have larger central bank balance sheets, relative to their economies, than we do (FRB = Federal Reserve Bank):

By many accounts, Sweden did a great job managing its financial and fiscal crises in the early 1990s. But more than 20 years onward, its unemployment rate is still higher than before the crisis, as noted in a recent commentary by the Cleveland Fed’s O. Emre Ergungor (ht: Torsten Slok):

And its labor force participation rate is still lower:

Does Sweden’s experience portend similar problems for the United States? Ergungor thinks not. Instead, he attributes this shift to a structural change in Swedish policy that has no direct analog in the United States:

One study of public sector employment policies published in 2008 by Hans-Ulrich Derlien and Guy Peters indicates that for many years, the labor market had been kept artificially tight by government policies that replaced disappearing jobs in failing industries with jobs in the government. The financial crisis was the breaking point of an economic system that had grown increasingly more unstable over a long period of time. It was a watershed event that marked the end of an unsustainable structure and the beginning of a new one. Public sector employment declined from 423,000 in 1985 to 240,000 in 1996 mainly through the privatization of large employers—like the Swedish postal service, the Swedish Telecommunications Administration, and Vattenfall, the electricity enterprise—and it has remained almost flat since then.

With such a large structural change, what came before the crisis may no longer be a reference point for what will come after. Having corrected the root of the problem, the Swedish labor market is now operating at a new equilibrium.

That doesn’t mean smooth sailing for the United States, as he discusses. But it does leave hope that perhaps we do better than Sweden in creating jobs in the wake of a financial crisis.

The U.S. economy has recovered slowly since the official end of the Great Recession in 2009. Mark Lasky and Charles Whalen of the Congressional Budget Office just released a study asking why. Their answer: two-thirds of the slowness (relative to past recoveries) reflects weak growth in the economy’s potential. The potential labor force, capital stock, and productivity are all growing less rapidly than they did following past recessions. The other third reflects cyclical weakness, particularly in government, housing, and consumer spending.
